Hi! A quick question, if I may.

What does the “regular” Purple Dragon salute look like?

I recall from the novels they raise their swords before a battle, but I assume they don’t wave the blades around like that in everyday situations (e.g. reporting)? Hi! You assume correctly. ;}
Left hand (flat open, back outwards, NOT a fist) swung over and slapped against the center of the chest. Purple Dragons who lack a left arm for any reason do a high-stepping "march step" in place, in lieu.#Realmslore
